Compare y = 4x - 3 to the standard
y = mx + b.
You can see immediately that the slope, m, is 4 and that the y-intercept, b, is -3. The error lay in the explanation (see the problem statement) that the y-intercept is 3. That's not correct.
Answer:
The inverse operation of squaring a number is finding the square root of a number. The square root cancels out the square. For example, 3² = 9. To cancel out the square, we have to take the square root. So, √9 = 3. Hope this helped.Step-by-step explanation:
3x^2 - 7x + 12 = 0...move the 12 to the other side
3x^2 - 7x = -12....now divide by 3
x^2 - 7/3x = -4..this is where he made his mistake
